COMBINED LIGHTING AND IGNITION SWITCH.

Application filed December 15, 1913. Serial No. 806,752.

To all whom it may concern.

Be it known that 1, WILLIAM KAISLING, a citizen of the United States of America, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Combined Lighting and Ignition Switches, of which the following is a specification.

My invention relates to electrical switches in general and has to do more particularly with so-called combination lighting and ignition switches ordinarily used on automobiles. That is unit switches of that character wherein a single frame-work is provided for supporting the switch mechanisms for controlling the ignition and lighting circuits. In devices of this character, it is important that the control of the different circuits be automatic so far as possible and that the number of operations be reduced to a minimum and to this end I have provided a device of the above character having two operating levers for controlling the lighting and ignition circuits respectively together with a third or starting switch which is also controlled by the actuating member of the ignition switch. Another object of my invention is to provide a switch of the above character in which a so-called dimmer switch is combined with the lighting switch for controlling the brilliancy of the lights. A further object of my invention is to provide a device having the above characteristic, which is compact, easily accessible to all of its working parts, and positive in its operation.

Referring now to the accompanying drawing in which I have illustrated my improved structure,

Referring now in general to my invention as illustrated it comprises a lighting switch L and an ignition switch M, the lighting switch having a normal position A and preferably three operative positions B, C and D whereby three combinations of lights can be connected in circuit. The arrange ment of the lighting switch is such that when its operating lever is moved to the position B, the side, tail and speedometer lights are lighted and when the operating lever is moved to the position C, the head, tail and speedometer lights are lighted. Now when the operating lever is thrown to its position is the-last position, all of the'liglits are lighted, but I do not WlSll to be limited to this particular arrangement asmany different combinations can be in'z ide' 'without' departiri from the invention.

The'i'g n'ition switch rests normally in an inoperative position E it having preferably t-wo operative positions F and G as shown, and when the ignition switch is moved into its position F the battery igniti'oii is iituse and-when moved into its position G. the magneto ignition is'in use.

A starting-switch SS (Figs; 4- 11) is also provi'ded': which is used with a uni-spark systern as illustrated in Fig. but when the starting switch is operated it converts the uni-spark system into a vibratory'system to throw a shower of sparks to give an etl'ectiile "st: irting circuit. This starting switch is'al sd'arranged sons to close a circuit for a starting motor to start theeugme suchas is usedi--'-in th'e well -l'cnown*Delco self-starting y it. i g "'I'jalsoprovide a'dimmer switch D5 which is operatedrby turniug" a-knob to the. leftor right and when the dimmer switch is inf-its normal or eflective position, (in which positioxi the-'Jwiper is not engagin its contacts) the cu'm-entis carried throug a resistance wlriQhredLices the'curieiit flow through the hegdliglits dirnming them; 'When the wiper 0f the dimmer switch isthrown into its operative-position to engage its contacts it short circuits the resistanceand allows the full current fiowt'opass through thehe'ad lights giyihgthenr'their full can'dle power.

'alsolprovide a locking ii'iech anism which consists preferably of a standard Yale tumbler lock which controls 'two's'liding pla'tes which are'ad'aptec'l to lock the lighting and ignition switches, the diinmer switch, and also a horn c'i'it ou'tl The'lo'cking niecha nism is so arranged that it operates only when the'switch M is inits'norinal or ino'perative position I), and when the ignition switch lever is in eitherits l or G position the lock cannot be turned by the key. N ow if the operator attemptsto operate the lock hejis at 'once aware that the ignition switch is in an operative position and must he moved to its inoperative -position E so that the lock. can be operated and the key withdrawn.

The locking arrangement of the lighting switch is so constructed that the key may he turned to lock the lighting switch in an of its lighting positions so that the operator can leave any combination of lights lighted and still lock the lighting switch against operatiou.

he startin" switch SS is also controlled against operation as it is preferably worked in combination with the ignition switch and therefore cannot be operated when the ignition switch is locked in its inoperative position. I r

' The dimmer switch DS may also be locked in either its effective or nonetl'ective position by the same look and and w lren,the lighting switch is locked in anyof i'ts'operated positions, the said dimmer switch is also locked against operation.

A horn cut-out llC (Fig. 9) is also con trolled by the said locking mechanism and when the lock is in its unlocked position the horn is in circuit but-when the lock is'opei ated to lock the switch the'horncircuit is opened. a

Referring now more in detail to my invention as illustrated, it comprises preferably a mounting base :or plate 1 made of suitable insulating material andlia.ving studs 2 and 2 fastened to it'im anysuita'ble mzumer preferably as illustrated?in Fige' 8, said studs having a. portion: "extending through the plate 15 threaded toiieeeivelth'e nut 3. A stud- 2 is provided for the lightin switch L and a-studi2 for the ignition switch M. i l

The lightingswitch L comprises a shafb4 having a=bear1ngL-5 and carryingial wiper 6 which is insulatingly mounted on'tli'eshaft l, the said wiper'comprising blades==6 and 6 which are cliiiiiperl upon"thesha ft lby means of a nut fzi lhe blade- 6 ascleauly illustrated in'Fi-gr -1'0, hasiits top addlbott'om' surfaces made=up1of-twoisegmehts- 6 and 6, said segments being) :insulatingly mounted; rivets 6 passing =thro\igh i the"r i nsirl'ati ng bushings, b'ut not'electrically connec'fiing the segments 6? and 76 this wi 'r blade is"constructed so as aoopeiate with' theflinnfiirig of the head lights, as-will be 'more'-full v de'-' scribed in other rts of'tliespe'cificationi I provide a yieldino'i holding device for holding each of the switches in t he'ir difikfi ent positions this lioldi'n'g-devioe bein'g in the form of a notched or'tootheddisk 8 wh iehi's' also firmly clamped 'upon the' shaft'l bymcans of the'nuti; To hold the disk 8'-andthe wiper 6 in the same relative position 'sg l provide a pin 9 which-is forced uh o'aglmhe disk 8 anchinsulated from thewiper fi by a bushing. place on the stud 2 ilZTQSlIS-flgfiiilfilt the pl'a te' 1 Co-operating with-thewiper blades f6 and 6 of the lightswitch Laro the' segmental contact strips .10; 11, 12, 13, an'd 14-2531- lustrated in Figs.- l4;and 15. 'Ihe'seg'nients 10, 11, l2, l3 and 14: have extensions 'm 11 121, 13*, 1a= and114 in theforin of contact ends which operate iii-connection with the wiper-blades 6 and 6 'toive the different combination 0t lights.

\Vhen the lighting switchis in.

. h segment 13 is common-having the'e'xt'ensi'ons' 13 and 13 which are related to the contact strips 10 and 11. The contact ends 10, 11 and 12 operate in connection with the top Surface of the wiper blades 6 and 6 and the said segments 10, 11, 12 being connected to their respective terminals 10 11 and 12 shown in Fig. 3. The contact ends 13, 13 and 14 operate in connection with the bottom blades or surfaces 6 6 of the wipers 6 and 6 The strip 13 carries contact ends 13, 13 and is connected to the terminal 13 through the clamping screw 15 and strip 15. The segment strip 14 has an extending portion 14 arcuate in shape which operates in connection with the dimmer switch wiper 16, the strip 17 also co-operating with said wiper which is adapted to connect the two elements 14 17. Segmental contact strip 17 is connected to the common strip 13 by a metal washer 18 as illustrated in Fig. 16. The member 14 has an ear 14 which carries a stud 19 tapped to receive the screw 20 which serves as a bindin post for one of the terminals of the resistance element 21, the other terminal of the resistance being fastened to the com mon strip 13 by means of the clamping screws 15, (Fig. 4). The strip 13 has an extension 13* (Fig. 16) operating in connection with a contact strip 49, the said contact strips 13 and 49 operating in connection with wiper 31 of starting switch SS.

Now when the lighting switch is in its normal position A, there is no connection between the wiper blades and the contact segments but when it is moved to its position By the contact segments 10, 11, 13,

13 are connected as shown in Figs. 14 and 15 giving one combination of lights. ;Now if the lighting switch is moved'toits position C, the contact segments 11, 12, 13 14 are connected as shown in'Figs. 14 and 15 giving a second combination of lights, and when the lighting switch is moved to its position E the contact segments 10, 11,

12, 13 and 14 are connected as shown in Figs. 14 and 15 giving the third combination of lights.

Referring now to the ignition switch M, this is similar in construction to the lighting switch L except that the notched disk 8 differs, as does the wiper 22, said wiper having one wiper blade 22. In addition, the shaft 4 carries a cam 23 which operates in connectio with the starting switch and which will be more fully described in another part of the specification. Corre spending with the wiper blades 22 are the segmental contact carrying strips 24, 25, 26 as illustrated in Figs. 17 and 18. The strips 24, 25 and 26 have extensions in the form of contact segments 24, 25, 26 and 24 The contact segments 24, 25 operate in connection with the upper surface of the wipcr blade 22. The strip 24 is connected to its respective binding post 24 as illustrated in Fig. 3 and the segment 26 is connected to the terminal 13 through the clamping screw 27 and strip 15. The contact segments 26 and 24 operate in connection with the bottom surface or the wiper blade 22. The strip is connected to its respective binding post 2'' as illustrated in Fig. 3. hen the lever of the ignition switch M is moved to its position F the contact segments 25 and 24 are connected through the wiper blade 22, and when the ignition switch member is moved to its position G, the contact segments 24 and 26 are connected through the wiper blade 22. The strip 25 has an extension in the form of an arcuate contact strip which co-operates with the wiper 31 of the Starting switch SS. A companion contact strip 32 arcuate in shape, also operates in connection with the wiper 31. The segment 32 is connected to its respective binding post 32 as illustrated in Fig.

For controlling the lighting and ignition switches L and M, I provide the handles or levers 28, and 29 fastened to their respective shafts 4 and 4 by means of the screws 30.

In order to yieldingly hold the lighting and ignition switch members L and M in any of their operated positions, I provide a holding device T (Fig. 20) which comprises a centrally pivoted member 33 which carries the rotatable rollers 34 and in its bifurcated ends, the said rollers 34 and 35 op erating in connection with their correspond ing notched disks 8 and 8. The member 33 is pivotally supported at its center by a stud 36, which is suitably fastened to the plate 1 preferably by having the end that protrudes through the plate 1 threaded to receive the nut 37. The free end of a spring 38 rests against the bridge of the member 33, the other end of the spring 38 being fastened to the plate 1 by means of the screw 39 and nut 40, the spring pressing the rollers 34, 35 against their respective disks 8 and 8. When one of the switch members is operated the teeth of its disk are rotated against the rollers 34 or as the case may be and due to the action of the spring 38. and as the disk advances, the roller acts upon the next toothed notch so as to give a snap action to the switch member and at the same time hold the actuating members of switches L and M in place. The cap 73 en closes the apparatus, this cap at the same time holding the members I1 and Ni in position upon their respective studs 2, 2. The cap is placed over the apparatus before the levers 28 and 29 are attached to their respective switches and before the knob 56 is placed upon the shaft 50 of the dimmer switch. The stud 36 has a shoulder 36 which rests against the member 33 to keep it in position with the disks. the bottom of the member 3;) bearing against the plate 1. The starting switch SS works in connection with the ignition switch M, a plate 41 (Fig. 20) being provided-and'haviug a bearing 42 attached'to it in any suitable manner and being-of such a size as to fit the extension 36 ofthe stud 36. The plate 41 also carries a roller 43 by means of a pin 44. The roller 43 operates in connection with the cam 23 (Fig. 11), the said cam '23, as already described, being mounted upon the ignition switch operating member. -\n extension 41 of the plate 41 has a notch 41 to receive one end of a restoring spring-45. the other end of the restoring spring being placed in a notch 46 of the washer a t; which is held in place by the clamping screws 47 as illustrated in Figs. 4, 7 and 11. An opening 41 is provided in the enlarged portion of the plate 41 to allow the shaft of the dimmerswitch to pass through. The wiper 31 is insulatingly moun tedupon the plate-41being-fastened thereto by means of rivets The starting switch may be operated when the ignition member M is in either its battery position F or magneto position G.---Wh en moving th eignition switch to its batteify position an added upward pressure (F i'gz ll') upon the lever 29 fo rce's the roller- 43 to ride upon the cam surface 23 of thecam 23, the plate 41 swinging upon its pivot and carrying-the wiper 31 with it from between the contact-segments 25 and-32'a'nd placingsaid wiper 31 between the contact segments 13 and 49 which operation will be further described in connection with Fig. 23. i i

Fig. 11 illustrates the starting-"switch in its operated position when the ignition switch'is moved to its battei'y 'position F.-

but the starting switch may alsobe operated when the ignition switch is'moved to its magneto position G. Added downward pressure upon the lever 29 forces the roller 43 to ride on the cam surface 23 of the'cam 23 thus operating the switch SS as before described. When the pressure isreleased the spring 45' restores the plate 41, thus restoring the starting switch to its actuated battery position or-magneto position, as the case may be. The wiper 31 again rests in its normal position between the contact strips 25 and 32.

Now referring to the dimmer switch il lustrated in section in Fig. 22, it comprises a shaft having an enlarged portion 50 upon which the stop 51 is mounted, the stop 51 having two notches 5'1 and 51 which notches co-operate with the locking mechanism to lock the dimmer switch in either its normal or operated position. The .sto has an arm 51 which works to the rig t or left in a V-shaped groove 52 in plate 1. the arm 51 being thus limited in its movementto the right or left by engaging the edges 52 or 52 of the groove 52, (Fig. 12). The wiper it; of the dimmer switch is insulatingly mounted upon the shaft 50, being clamped on said shaft by ine ans'of the nut 5 The portion of the shaft 50 extending through the plate 1 is drilled and tapped to receive a screw' 54; tension washer 55 being hlaced between the Screw 542ml a washer. the tension washer aliowing the dimmer switch to be easily operated to the right or left but therebyheld in its operated position. knob :36 is suitably fastened to the 'stud 50.

A locking arrangement is provided whereby the lighting and 1 ignition switches L and M maydie locked in different positions and I therefore provide a- Yale tumbler lockW/f, fastened to the cap 73. As illustrated in'Fig. 21, thisYale lockjis inodi fiedhy the addition of'a pin-=57, which is eccentrically disposed on the cylinder- -58 of the lock so that whenthe key 59 is turned the pin moves about the'cent'er of the cylin der 58. A connecting m'echan'ism is"pro- .vided between the lo'clc' and theswitchmem hers wherebythe actuatingfmeinbers or L, M, DS and SSc'an be locked. Itlierfore provide the sliding plates some 31 which are *held in the 'plate l" by me'a ri's"- or are shoulder screws 62 and .63 which extendthroughslots 60 and 1 60 and through the plate 1' into the nuts 6 4iv Thpla es 60and 61; are connected toea'ch otliei" meansof thesti id 6h. The plate 60 is aU sliaped member having" the'eiitende'd portions res't ing in grooves; 66 and 67 and'also having projections K20 "and 7 60 which t d-sperm with the disks 'B'aiid 8 'respectivel'y to iock" the switch i' embers- Ihave preferably arranged the ignition" the disk 8 has four slots 8, 8 8 and '8,

whereby the lighting'switch may .belock'ed in its normal or any of its three operative positions. Theai fm 8 of the 8 limits the movement of' the lighting switch ncinber in its normal position, the smegma 8' engaging the extension 60 of the plate 60 but when in itsposition D, the "curved .portion of the arm 8 engages the roller 34 to limit its forward movement. To limit the movement of the ignition switch in its operative position 'F,'the curved surface 8 of the 'disk 8 engages the roller 35 limiting the novement in this direction, and when operating the starting switch SS by lever 29 when in its position G, the surface 8 engages the extension 60 of the plate 60. Tlie'plate 61 is connected to the plate 60 and rests in a guiding groove 68 and has an extension 61 which is adapted to moveinto the notches 51 or 51 of the dimmer switch when the lock is operated to prevent the dimmer switch from being moved.

In Fig. 12 I have shown the locking mechanism and operating members of switches L and M in their normal positions and in Fig. 13, I have shown the locking mechanism operated and the operating members of L and M and dimmer switch in their normal p sitions.

I also provide a horn cut-out H0 which is operated in connection with the locking mechanism. The plate, (-31 is provided with a slot 61 having at its lower end an angular surface 61 (Fig. 9) which co-operates with an insulating button 69 carried by the spring 70. The spring 70 is fastened to the plate 1 by means of the screws 71 which onnect the spring to its terminals 13 illustrated in Fig. 3. The spring 70 carries a contact 70 which is normally closed with a contact. 72 which is connected to a terminal 72 as shown in Fig. 9. To operate the horn cut-out, the lock in operating carries the plate 61 upward. the button 69 riding upon the angular surface 61 and opening the contacts170 and 72. i

The spring 70 by its button 69, which lies in the path of travel of the,plate 61 ,and cooperates with the angular surface 61 of said plate prevents the locking mechanism from being accidentallydisplaced and from rattling which mightotherwise very read ily occur fromfjarring. Wheii'the keyfis turned to locked position. the spring '70 also holds the locking mechanism, yieldingly in position. the button 69 then engaging the surface of the plate 61.

Assuming now thatfthe ignition switel M,is in its, position F and the lighting switch member is in any of its operative positions, if the key is inserted in the lock and an attempt made to operate the lock, the key can be turned just a trifle or until the projection 60 of the plate 60 will come in contact with the periphery 8 of the disk 8 The key cannot be withdrawn 'and this unsuccessful attempt to turn the key will immediately indicate to the operator that the ignition member M is in an operative position. To lock the two switches L and M. the member M must be moved back into its inoperative position E. When in this position the notch 8 registers with the projection 60 of the plate 60 and the key can now be turned. The pin 57 turns with the cylinder 58, the pin working in the opening 160 of the plate 60 moving the projection 60 into the n tch 8 of the. disk 8 and moving the projection 60 in any one of the notches 8 8, 8 or 8 depending in which position the switch L is. It can be seen from the above that the lighting member can be locked in any of its positions when the member M is in its position E, but the switch M can be locked only when in its position E.

The locking of the switch M of course prevents actuation of the starting switch and the mo\ ement of slides 60, 61 will lock the dimmer switch DS in either one of its positions.

In Fig. 23. I have illustrated a circuit arrangement adapted to operate in connection with the switch described, the switch parts being shown diagrammaticab ly and in their normal positions. like reference characters denoting like parts so that the description of the operation may be easily followed.

Referring now to the ignition switch M. I hare shown it connected with an ignition circuit IC comprising an interrupter 73. a distributor 74 connected to four spark plugs 75, an induction coil 76, a battery 77, an ignition relay 78. and a second or magnet charged battery 86.

The general operation of the ignition switch is as follows: Assuming that the ignition switch M is in position F, and the engine running. each time the contacts 79 and 80 of the interrupter are closed. and the distributor 74 connected to one of its contacts, a circuit is closed through the low resistance winding 89, (winding 81 being normally short circuited through contacts 32. 95" and 83) and through the contact strips 24 and 25. The operation of the relay 78 causes the interruption of its normal contact 83, whereby the energizing circuit. is broken through the low resistance winding 92 and primary of induction coil 76 to effect a spark at the connected spark plug. the relay 78 then being held energized through its high winding 81 until the con tracts at the interrupter are broken. when the relay restores being again energized each time the interrupter contacts and the distributer contacts close.

Now if the ignition switch M is in its position G. with the contacts 2'4 and 26 connected, each time the interrupter contacts 84 and R5 and the distributer contacts are closed, a spark is effected at the connected spark plug by current from the storage battery 86, which battery, (in the well-known Delco system) is charged by generator T, the charging connections of which are not shown here. The ignition relay 78 is not used in c nnection with the switch M in its so-called magneto position. as the current from the magneto charged battery 86 preferably flows direct. through the primary winding of the induction coil, and depends upon the break at contacts 84, to produce the spark.

Now if the engine is not running and the operator wishes to start it, he throws the ignition s itch M in either its position F or G. When thrown in position F further pressure applied It; the l rer 2.! mo es the starting switch $9 to it alternate position to connect the wiper 31 across the contacts 1 3 and 49. The opening of contacts and .25 interrupts the energizing circuit of the high resistance or holding winding 81 of relay 78, but lou rcSiStanrtnintling S2 is still in circuit to be energized and as the Contact 83 is included in the circuit of winding 82. the armature of relay 78 vibrates mpidlytoproduce a plurality of sparks for startingthe engine. The Closing of the contacts13 and 49 by the additional inorenicnt 0f switch Mclqses acircuit for the stutarm tor T from battery 8 h thus Starting the engine which is connected t the motor as in 'the well-known Delco selftarting system. As soon as the pressure on le er '29 is released by the operator. the nipcr of the ignition member M again assumes its positiomconn ecting the contacts 24 and 25. thus' again connecting the ignition relay 78 in-the uni-spark system.

.zw'hen the switchmember of M is m0 'e(l totitsposition G-and addeddownward pressure-applied to the lever 29. the contacts 13 and 49. are again closedas before connecting battery 86 to mptor T which rotates and starts-the e ine. In this case the battery 86 used. irectly through the primary wintii oi the induction coil for producing the ignition sparks.

Now-as to the lighting switch I. I have illustrated a lightingsystem. in connection with it. comprising the head lights H. the sidejights S. and the tail and speedometer lights-Wendy, the battery 86, and the protect ive fuses: 8K 88, and-89. I show a horn 9t) in circuitwith. tr horn cut-out HC. and a button 91'.foroperating the horn. \Vhen the switch member 28 is moved to its position B, the side lights, and tail and speedometer-lights are lighted. the wiper hlade 6' having its segments 6 in contact \\ith the contact segments 11 and common segment 12. segment 6 then being in contact with the contact segment 10 rind comm n *0;- ment 13. The circuit.of the side lights extends from ,liattery 86 to the contacts 10' and 13. and wiper blade segments thr ugh the said. lights in multiple through the protective fuse 88 to ground, and the circuit f r the tail and speedometer lights extends from batte'ry 86, contacts 11, 13 the segment 6 of theqviper throughthe tail and speedometer lights through the protective fuse to gimme. The tail and speedometer lights are preferably in series so that the operator can tell fr'm the speedometer light whether the (Hit lig t is lighted. Now when the lighting switch member 28 is moved to its position C. the tail and speedometer and head lights are lighted. the wiper blade 6' hav ng its segment i in contact with contact segments 12 and 14, and the segment 6 in ontact uh thc routuC-t segment 11' and common 13. The dimmer switch may be l|t'(i in connection with the head lights H ml hen th wiper of the dimmer switch is its ncll'et-tixe position, the current for l ghtin aid head lights passes through the t't:-:-t::nu' 21 lo dimthc head lights.
